• Is the memory size large?
→ The memory check may take a few seconds if the memory size is large. Wait for a while.
• Did you perform any keyboard or mouse operation immediately after you started the server?
→ If you perform any keyboard or mouse operation immediately after start-up, POST may accidentally
detect a keyboard controller error and stop proceeding. In such a case, restart the server once again.
Do not perform any keyboard or mouse operation until the BIOS start-up message appears when you
restart the server.

• Are cables properly connected?
→ Make sure that the interface cables and power cord are properly connected. Also make sure that the
cables are connected in the correct order.
• Is the power-on order correct?
→ When the server has any external devices connected, power on the external devices first, then the
server.
• Did you install drivers for connected optional devices?
→ Some optional devices require specific device drivers. Refer to the manual that comes with the device
to install its driver.
• Is BIOS configuration correct?
→ When the server has PCI devices connected, make sure to set the PCI device interrupt and others with
the BIOS setup utility of the server. (Most PCI devices generally do not require any change to the
configuration, but some boards do require specific settings. Refer to the manual that comes with the
board for details to make correct settings.
→ Some devices connected to the serial or parallel port may require I/O port address or operation mode
settings. Refer to the manual that comes with the board for details to make correct settings.
